hiperArc stops authenticating
by Lewis Bergman 27 Mar '03

27 Mar '03

I noticed my TC stoped responding to my RADIUS server. The symptom was that users already connected stayed connected. Users dialing in get a failed password. My RADIUS server sees the first auth request and responds and then starts dropping all the duplicates it starts to see. In a haste to get it back up I rebooted and see the syslog entry below. HiPer>> list syslogs SYSLOG SINKS SysLog Log Level Facility Buffer Allow all Count Auth levels 208.29.17.252 CRITICAL LOG_AUTH 100 YES When I do a show syslog 208.29.17.252 it comes up empty. Anyone got any ideas or do I just need to wait until it happens and read the log before I try to clear the problem. -- Lewis Bergman Texas Communications 4309 Maple St. Abilene, TX 79602-8044 915-695-6962 ext 115

RE: [USR-TC] Nat on Total Control 1000

Add a network to either eth1 or eth2 that is on the same subnet as your dialup users. I believe then it will route from one subnet to the other. Here's an example of what's running on my rack, basically the reverse of what you're trying to do, but it works: ARC eth1: 216.81.189.29 user ip pool: 96 addresses starting at 216.81.189.30 ARC eth2: 90.0.0.2 When a user dials in and gets a 216.81.189.x address, they have full access to any 90.0.0.x address without any problem at all.

Average Connect Speed
by Jim Sheldon 26 Mar '03

26 Mar '03

I just want to compare some data. I average the connect speed for all my calls across both my TC chassis each month. I then compare that to the average connect speed of each channel on my DSP's as a check for a problem DSP channel or T1 channel. I have been tracking it for a while now and the rough average is 38k. I would like to see what others might be averaging. I understand that the ratio of urban to rural users, etc. may skew the numbers. We are using 3.5.105 for our DSP code with v.92 enabled.

Software compression?
by Joshua Coombs 26 Mar '03

26 Mar '03

I have a pool of 8 TC1000 chassis, using DS3 ingress to a full payload of multispan DSPs on each unit. AFIK from what the arc is reporting, software compression should be disabled for anything other than ISDN (digital) calls. Well, after seeing the thread on this list re software compression, I decided to run some tests to see if turning it on would improve things for our customers, much to my suprise I see that even though compression is set to digital only, it appears to be working for analog callers anyways. Below is version / ppp setting output from one of my TCs (they all have matching confs) as well as my test data. Speedtest.gwi.net is web accessable, and just streams a set amount of text then reports the transfer rate, nothing fancy. Is there a flaw in my testing or is something screwy going on with my TCs?

port parameters
by alex 26 Mar '03

26 Mar '03

set switched interface slot:X/mod:Y connection_type Direct_net - Uses the protocol parameter’s setting to create a network (virtual node) connection. Employs user name and password specified in this command. Authentication is done by the network protocol such as PPP. Direct_net does not support the SLIP protocol. If I set connection_type to direct_net how users will be authenticated? As I can get from this description user must be authenticated twice - first with user/pass from interface (this user/pass is only sent to radius, user don't have to know this user/pass) and second by ppp authentication (completed on user site, user has to enter correct user/pass from radius). Am I right?

Watchdog timeout
by alex 25 Mar '03

25 Mar '03

Why when watchdog timeout occures on a card this card is rebooted? Watchdog timeout occures after Management bus failure (often)? Will the card reboot if I set static configuration on (H)ARC (like set chassis slot x type static ...)? If not what can I do to stop card reboots?

Software upgrade
by Alexander Jaliashvili 22 Mar '03

22 Mar '03

I want to upgrade my chassis from TCS 4.3 to TCS 4.5 Now I have HARC with 64Mb ram and 8Mb flash. NMC_CLK with 16Mb ram and 8Mb flash (HW ver 6.0 soft compab. v 7.0.0). HDSPs 8Mb ram 2Mb flash. I want to upgrade this chassis because of modem "freezing". Do I need hardware upgrade too? If yes what I must upgrade? Is it possible DSPs to be TSC4.7 , ARC and NMC to be TCS 4.3?
